which is made up of separate parts each of which is removable. A chimney constructed inaccordance with this invention may be erected dry. That is to say, no mortar need be used, and the whole can be aseasily taken down for the renewal of all or any broken part. made as herein set forth is able to furnish them in knock-down condition, each part being usually made of cement or the like, and the whole to be assembled on the job, as the blocks or members fit into place making a very rigid chimney without using mortar, and which can readily be repaire by replacing any one of the members without upsetting the entire chimney.

The various parts of this invention are of special construction and arrangement, and

the forms and disposition thereof are illustrated in the accompanying drawings of which Fig.1 represents a side view of all parts assembled, the near left hand corner of the chimney being broken away to disclose interior members. Fig. 2 is a side View of one of the vanes by itself. Fig. 3 is an edge view from the top or beveled edge portion of the vane. Fig. lis a cross-section of one of the corner uprights taken on the broken line 44:. of Fig. 1. Fig.5 is a top view of one of the corner block members which are all alike.

Throughout the drawings and description the same number is used to refer tothe same 1 Considering the drawings, on a brick or other kind of base 1, are standing four corner uprights 2 in vertical position and all alike. On adjoining faces each has the L-shaped downwardly and outwardly extending grooves 3 and 4. While L-shaped grooves are shown in the drawings, it will be understood that dovetail grooves may be vanes 5. Each vane has the side flanges 6 A manufacturer of chimneys Engaging the grooves are constructed to enterjthe :grooveaand each vane, has a narrow edge or top' 7 terminating a beveled surface 8.

tension YtO with a dovetailrecessll, and .a second side extension 12 on the adjoining 'side provided with a like dovetail recess 13'. lit may be here'stated that if it is desired the top blocks may be provided with dovetail seats14fand an additional chimneygcap or top-"fastening can be employed, not 3 shown int'he drawings. V

Considering Fig. 1, one of *theintermedia'terblocks "15 is show-n in detail. Each intermediateblock has on opposite sides the cavities 16, and the downwardly projecting dovetail lug 17. It will also be noted that the lower and inner corner of the intermediate block 15 is given an inclined surface 18 downwardly and outwardly. It will be further noted that the surface 18 is the upper wall of the upper air channel of the chimney. Each of the side extensions 10 and 12 of the corner blocks 9 are provided with surfaces having the same inclination as 18, and in Fig. 1 it will be noted that the uprights are given a pyramidal form at the top such as the top end 19 of theupright 2. Inlother.

words, the two meeting sides of each upright that form the outer corners of the chimney are cut away at the top as illustrated in Fig. 1 showing one side of the pyramidal top end of the upright, that end being marked 19.

WVhen the various parts are assembled, the

flue 20 of the chimney is substantially unbroken, the beveled surfaces 8 of the vanes being presented inwardly and vertically.

The corner blocks 9 and intermediate blocks 15 form the' chimney top. It will be understood that the corner blocks may be placed and by its weight and construction it notonly secures the uprights in place and itself in position thereon, but the corner blocks and intermediate blocksare additionally secured by reason of the wedge action of the pyramidal tops of the uprights, and by the fact that the lugs 17 are dovetail devices. It will be understood that no mortar is used in this assembly, and that a variety of vconstructed to engage the grooves'of the uprights thereby affording upwardly inclined air channels between them, and a chimney top formed of separable members constructed to engage each other and to en.- gage the said uprights, the said uprights and chimney top having upwardly and inwardly inclined portions in contact whereby the weight of the top exerts an inward pressure on the uprights.

2. In a chimney, the combination with corner uprights, of removable vanes, the said uprights vand the said vanes being provided with devices mutually engaging each other and securing the uprights and vanes together in detachable relation whereby the uprights are held against separation in the direction of the length of said vanes, a chim-.

neytop having corner pieces and intermediate pieces, the said corner and intermediate pieces having means carried by them for securing them 'removably together, and the said chimney top being constructedto engage the said uprighta. f

3. Ina chimney, the combination with cor- -ner uprights, of removable vanes arranged between the uprights, the said uprights having pyramidal. top ends, a chimney top constructed with separable corner pieces having internal inclined surfaces arranged to engage the said pyramidal top ends of the uprights whereby the said chimney top is retained in place.
